Изобретение относитс к кабельной технике.The invention relates to cable technology.

Цель изобретени - снижение расхода меди токопровод щих жил низкочастотной св зи.The purpose of the invention is to reduce the consumption of copper conductors of low-frequency communication.

На чертеже показан кабель, поперечное сечение.The drawing shows the cable, the cross section.

В пазах крестообразного сердечника 1, имеющего центральную симметрию , располагаютс неизолированные токопровод щие жилы высокочастотной пары 2 и низкочастотной пары 3, Сердечник кабел заполнен изол ционным материалом 4. Дл обеспечени высокой помехозащищенности центры всех токопровод щих жил расположены строго по углам квадрата и рассто ни а и а между ними равны.In the slots of the cruciform core 1, having central symmetry, there are uninsulated conductors of high-frequency pair 2 and low-frequency pair 3. The cable core is filled with insulating material 4. between them are equal.

Это достигаетс тем, что рассто ни от вершин внутренних углов сер дечника, образованных его боковыми гран ми, до центра симметрии св заны соотношениемThis is achieved by the fact that the distances from the tops of the inner corners of the core, formed by its side edges, to the center of symmetry are related by the relation
